Hello. Is anyone related to English born John William Jennison? He was an author of many fiction stories, western novels, science fiction in the early 1950s and then in the 1960s obtained some fame for writing the books to the THUNDERBIRDS series, STINGRAY series, etc.
He may have died as early as 1969, which is the date of the last known book to have carried his alias, John Theydon. He wrote under many other pseudonyms, too. To my knowledge, the earliest story he wrote was 1946, but almost certainly he appeared prior to that.
IF anyone is related, I should dearly love to hear from you. I do not know his birth or death data, etc.
